Description: THERMOPLASTIC ELASTOMERIC COPOLYMERS AND HAIR AND SKIN CARE COMPOSITIONS CONTAINING THE SAME TECHNICAL FIELD The present invention relates to water or alcohol soluble or dispersible thermoplastic elastomeric copolymers and to cosmetic and pharmaceutical compositions containing these copolymers. These copolymers are useful for hair setting and styling purposes. A particularly useful application for these copolymers is in hair spray and mousse compositions. This invention further relates to copolymers useful for incorporating into cosmetic and pharmaceutical compositions for topical application to the skin. Skin care compositions containing these copolymers are useful for delivering and/or transdermally transporting a wide variety of active ingredients to and/or through the skin. BACKGROUND OF THE INVENTION In the hair care area, the desire to have hair retain a particular style or shape is widely held. Such style retention is generally accomplished by either of two routes: permanent chemical alteration of the hair fiber or temporary alteration of hair style or shape. A temporary alteration is one which can be removed by water or by shampooing. Temporary style alteration has generally been accomplished by application of a composition to dampened hair after shampooing and/or conditioning and prior to drying and/or styling. Products in the form of mousses, gels, lotions, or sprays are most commonly used for this purpose. Once the desired style is achieved, spray products are commonly used to help retain the style. These various hair care products utilize a variety of gums and resins for providing styling and retention. However, the gums and resins currently used tend to feel either too sticky or too stiff upon the hair. Also, these gums and resins do not wash out as easily as desired. Therefore, the need exists for improved styling and style retention materials which provide a strong, lasting, hold without being either too stiff or too sticky, and yet which are easily removed by shampooing. Furthermore, because most hair care styling compositions are water and/or alcohol based, it is necessary that these materials have good solubility or dispersibility in these bases. Thermoplastic elastomeric copolymers are well known. These copolymers combine thermoplastic properties, which give them solubility and strength, with rubber-like elastic properties, which give them flexibility and shape retention. However, despite these highly desirable properties, most thermoplastic elastomeric copolymers are generally insoluble or poorly soluble in water and/or alcohol systems and would not be suitable in hair care compositions. Therefore, thermoplastic elastomeric copolymers having good water and/or alcohol solubility would be useful for developing improved hair care compositions. In the present invention new classes of thermoplastic elastomeric copolymers have been developed which have the desired flexibility, strength, and elastic properties and yet are readily soluble and/or dispersible in water and/or alcohol systems. Furthermore, these materials provide hair care compositions which leave the hair feeling natural, i.e. not stiff. In addition to the hair care benefits provided by these copolymers, it has been found that these materials are also useful for incorporation into a wide variety of cosmetic and pharmaceutical compositions for topical application to the skin. These copolymers provide topical compositions which are more easily and uniformly spread upon the skin, which feel good upon the skin, and yet which are highly substantive. Furthermore, these copolymers are useful for enhancing the penetration of a wide variety of cosmetic and pharmaceutical actives into the skin, or alternatively, through the skin for systemic delivery. It is an object of the present invention to provide novel, water and/or alcohol soluble and/or dispersible thermoplastic elastomeric copolymers. It is another object of the present invention to provide novel thermoplastic elastomeric copolymers useful in hair care compositions. It is another object of the present invention to provide novel hair care compositions having improved styling and/or hold properties and having improved aesthetics. It is another object of the present invention to provide novel thermoplastic elastomeric copolymers useful in topical skin care cosmetic and pharmaceutical compositions. It is another object of the present invention to provide novel topical cosmetic and pharmaceutical compositions useful for delivering a wide variety of cosmetic materials and pharmaceutical actives to and/or through the skin. These and other objects will become readily apparent from the detailed description which follows.

DETAILED DESCRIPTION OF THE INVENTION The term "thermoplastic elastomeric copolymer" as used herein means that the copolymer has both thermoplastic and elastomeric properties. The term "thermoplastic elastomeric copolymer" is one familiar to those of ordinary skill in polymer science. By "thermoplastic" is meant that upon heating, the copolymer softens and upon cooling it rehardens; upon being subject to stress it begins to flow and upon removal of stress it stops flowing. By "elastomeric" is meant that the copolymer has an elastic modulus such that the copolymer exhibits a resistance to deformation and has limited extensibility and retraction. In other words, the copolymer tends to recover its size and shape after deformation. The term "macromonomer" is one familiar to those of ordinary skill in polymer science, and is used to describe a polymeric material containing a polymerizable moiety. A macromonomer is a macromolecular monomer. A macromonomer is essentially a very large type of monomer building block unit which can be used in a polymerization reaction to foπn polymers with itself, with other monomers, or with other macromonomers. The term "water or alcohol soluble or dispersible" as used herein means that these copolymers are either freely soluble in or dispersible (as a stable suspension) in at least one of the following solvents, or alternatively, in any combination of one of the following solvents: water, methanol, ethanol, and isopropanol. By "soluble" is meant that the o copolymer is soluble in the solvent or solvents at 25 C at a concentration of at least about 20 mg/mL, more preferably about 50 mg/mL, and most preferably about 100 mg/mL. By "dispersible" is meant that the copolymer forms a stable, uniform suspension (without the addition of further materials such as emulsifiers) when combined with the solvent or solvents o at 25 C at a concentration of at least about 20 mg/mL, more preferably about 50 mg mL, and most preferably about 100 mg/mL. Thermoplastic Elastomeric Copolymers The copolymers of the present invention are characterized in having an elastomeric or flexible backbone and rigid, thermoplastic, hydrophilic side chains. This combination of both elastomeric and thermoplastic moieities in a single copolymer provides the unique and Useful properties of these materials. The copolymers of the present invention, can also be referred to as "graft copolymers" because they can be prepared from the copolymerization of monomer units and macromonmer units. In other words, the macromonomer is "grafted" or incorporated into the copolymer. These copolymers exhibit two distinct immiscible phases. Without being limited by theory, it is believed that the hydrophilic side chains of these copolymers are closely associated with each other, thereby existing in one phase, while the backbone of the copolymer remains in a separate phase. A consequence of this phase immiscibility is that these copolymers exhibit two distinct glass transition temperatures or, "Tg's", for the backbone and the side chains. Tg is a well known term of art in polymer science used to describe the temperature at which a polymer or portion thereof undergoes a transition from a solid or brittle material to a liquid or rubber-like material. Glass transition temperatures can be measured using standard techniques that are well known to the polymer scientist of ordinary skill in the art. One particularly useful technique for determining glass transitions is differential scanning calorimetry (also known as DSC). The glass transition phenomenon in polymers is described in Introduction to Polymer Science and Technology: An SPE Textbook, (eds. H.S. Kaufman and J.J. Falcetta), (John wiley & Sons: 1977), which is incorporated by reference herein in its entirety. The T α of the backbone of the copolymers herein (i.e. that part of the » o copolymer not containing the side chains) should be less than about 0 C. o Preferably the T α of the backbone should be from about -10 C to about - o a o o 130 C, more preferably from about -20 C to about -125 C, and most preferably from about -55 C to about -120 C. The Tg of the side chain of the copolymers (i.e. that part of the copolymer not containing the backbone) is greater than about 20 C. Preferably the Tg of the sidechain should be from about 25 C to about 200 C, more preferably from about 0 0 o 30 C to about 175 C, and most preferably from about 35 C to about 150°C. Because these copolymers possess two distinct Tg's, these copolymers are useful in hair styling and setting compositions. Without being limited by theory, it is believed that when these copolymers are subjected to temperatures above both Tg's, they are essentially liquid and can provide great flexibility during the styling process (e.g., when curling irons, blow driers, and other heat sources are applied to the hair). Upon cooling of the copolymer to room temperature (e.g., when the heat source is removed from the hair) the copolymer is then at a temperature that is typically between both Tg's, and the copolymer possesses structural rigidity from the macromonomer side chains, and yet has flexibility from the backbones, and can provide a strong, yet flexible, hair hold or style retention. Furthermore, at skin temperatures, these copolymers would be at a temperature which is essentially between both Tg's. These copolymers can enhance the film forming properties of skin care compositions, and provide benefits shuch as better and more even distribution upon the skin. The copolymers of the present invention are formed from the copolymerization of randomly repeating A and B units, preferably wherein the A units are selected from at least one polymerizable, ethylenically unsaturated monomer unit, and the B units are selected from at least one hydrophilic macromonomer unit which contains an ethylenically unsaturated moiety which is copolymerizable with A. In typical embodiments of these copolymers, the backbone is primarily derived from the ethylenically unsaturated portion of the A monomer unit and the ethylenically unsaturated portion of the B macromonomer unit. The side chains are derived from the non-copolymerized portions of the macromonomer. The A and B units can be selected from a wide vairety of structures as long as the limitations of the copolymer are met (e.g., solubility, Tg's, and molecular weights). The A monomer units of the copolymers of the present invention can comprise from about 40% to about 90%, more preferably from about 50% to about 85%, and most preferably from about 60% to about 80%, by weight, of the copolymers. The hydrophilic B macromonomer units can comprise from about 10% to about 60%, more preferably from about 15% to about 50%, and most preferably from about 20% to about 40%, by weight of the copolymers. The copolymers of the present invention have a weight average molecular weight of at least about 10,000. There is no upper limit for molecular weight except that which limits applicability of the invention for practical reasons, such as viscosity, processing, aesthetic characteristics, formulation compatibility, etc. In general, the weight average molecular weight is less than about 5,000,000, more generally less than about 2,500,000, and typically less than about 1,500,000. Preferably, the weight average molecular weight is from about 10,000 to about 5,000,000, more preferably from about 75,000 to about 1,000,000, even more preferably from about 100,000 to about 850,000, and most preferably from about 125,000 to about 750,000. Alternatively, the copolymers of the present invention can also be represented by the formula [ A ] a [ B l b wherein A and B are as described herein, and where a is an integer of about 100 or greater, preferably a is an integer from about 100 to about 3000, more preferably from about 250 to about 2000, and most preferably from about 350 to about 1500, and b is an integer of about 2 or greater, preferably from about 2 to about 50, more preferably from about 2 to about 20, and most preferably from about 2 to about 10. In this formula, it is expressly intended that even though ranges are provided for the subscripts a and b, these subscripts are not intended to strictly limit the polymers herein so long as the physical propoerties of the polymers are achieved. When the copolymers herein are described by the formula disclosed in this paragraph it has been found useful to describe the copolymers by their number average molecule weights. In general, the number average molecular weight is less than about 2,500,000, more generally less than about 1,500,000, and typically less than about 1,000,000. Preferably, the number average molecular weight is from about 15,000 to about 1,000,000, more preferably from about 20,000 to about 500,000, and most preferably from about 25,000 to about 250,000. By appropriate selection and combination of the particular A and B units and by the choice of specific relative ratios of the units well within the ability of one of ordinary skill in the art, the copolymers can be optimized for various physical properties such as solubility, Tg's, and the like, and for compatibility with other ingredients commonly used in hair care and skin care applications. When the copolymers of the present invention are incorporated into hair and/or skin care compositions, the copolymers typically comprise from about 0.1% to about 25%, preferably from about 0.5% to about 20%, more preferably from about 1% to about 10%, and most preferably from about 2% to about 5% of the composition, although higher or lower amounts can be used depending upon the particular application. Monomer "A" Units The "A" monomer unit is selected from polymerizable monomers, preferably ethylenically unsaturated monomers. Either a single A monomer or combinations of two or more A monomers can be utilized. For example, if two different A monomers are polymerized with a B macromonomer, the resulting copolymer could be described as a terpolymer. In either case, the monomers are selected to meet the requirements of the copolymer. By "polymerizable", as used herein, is meant monomers that can be polymerized using any conventional synthetic techniques. Monomers that are polymerizable using conventional free radical initiated techniques are preferred. The term "ethylenically unsaturated" is used herein to mean monomers that contain at least one polymerizable carbon-carbon double bond (which can be mono-, di-, tri-, or tetra-substituted). The A monomer units of the copolymers of the present invention can comprise from about 40% to about 90%, more preferably from about 50% to about 85%, and most preferably from about 60% to about 80%, by weight, of the copolymers. The ethylenically unsaturated A monomer units preferably can be described by the following formula o II X - C- CR 5 « -» CHR 6 wherein X is selected from the group consisting of -OH, -OM, -OR 4 , -NH2, -NHR 4 , and -N(R 4 )2l M is a cation selected from the group consisting of Na+, K+, Mg++, Ca++, Zn++, NH +, alkylammonium, dialkylammonium, trialkylammonium, and tetralkylammonium; each R 4 is independently selected from the group consisting of H, C-|-C8 straight or branched chain alkyl, N,N-dimethylaminoethyl, 2-hydroxyethyl, 2-methoxyethyl, and 2- ethoxyethyl; and R5 and Rβ are independently selected from the group consisting of H, C « |-C8 straight or branched chain alkyl, methoxy, ethoxy, 2-hydroxyethoxy, 2-methoxyethyl, and 2-ethoxyethyl. Representative nonlimiting examples of monomers useful herein include acrylic acid and salts, esters, and amides thereof. The salts can be derived from any of the common nontoxic metal, ammonium, or substituted ammonium counter ions. The esters can be derived from C ΛΛ straight chain, C3-40 branched chain, or C3-40 carbocyclic alcohols; 40 from polyhydric alcohols having from about 2 to about 8 carbon atoms and from about 2 to about 8 hydroxy groups (nonlimiting examples of which include ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, glycerin, and 1 ,2,6-hexanetriol); from amino alcohols (nonlimiting examples of which include aminoethanol, dimethylaminoethanol, and diethylaminoethanol, and their quatemized derivatives); or from alcohol ethers (nonlimiting examples of which include methoxyethanol, and ethoxy ethanol).

Most preferred A monomers are those selected from the group consisting of n-butyl acrylate, 2-ethylhexyl acrylate, N-octyl acrylamide, 2- methoxyethyl acrylate, 2-hydroxyethyl acrylate, N,N-dimethylaminoethyl acrylate, and mixtures thereof. Hydrophilic "B" Macromonomer Units A macromonomer is a large monomer unit, i.e. a macromolecular monomer, which can be further polymerized with itself, with other conventional monomers, or with other macromonomers. The term "macromonomer" is one that is familiar to the polymer chemist of ordinary skill in the art. The hydrophilic "B" macromonomer units of the present invention are very large monomer building blocks which can be formed from the polymerization of smaller monomer units. The B macromonomers encompass a wide variety of structures and are copolymerizable with the A monomer. Either a single B macromonomer or combinations of two or more B macromonomers can be utilized. In either case, the macromonomers are selected to meet the requirements of the copolymer. The hydrophilic B macromonomers comprise from about 10% to about 60%, more preferably from about 15% to about 50%, and most preferably from about 20% to about 40%, by weight of the copolymers. By the term "copolymerizable" as used herein is meant B macromonomers that can be reacted with the A monomer in a polymerization reaction using any conventional synthetic techniques. "Copolymerization" is a term of art used to refer to the simultaneous polymerization of two or more different monomers. In the present invention, B macromonomers that are copolymerizable with A monomers using conventional free radical initiated techniques are preferred. By the term "hydrophilic" as used herein is meant B macromonomers that are soluble in or have an affinity for water and/or other polar, water-soluble solvent materials (e.g., methanol, ethanol, propanol, isopropanol and the like). "Hydrophilic" is also a term of art used to described a substance having a strong tendency to absorb water which results in the swelling, solubilization, or dispersion of the substance in water. Without being limited by theory, the hydrophilic B macromonomer units are believed to contribute to the overall water or alcohol soluble or dispersible properties of the copolymers. B macromonomers that are useful herein contain an ethylenically unsaturated moiety that is copolymerizable with the A monomer. The term "ethylenically unsaturated" is used herein to mean B macromonomers that contain at least one carbon-carbon double bond (which can be mono-, di-, tri-, or tetra-substituted). Typically, the preferred B macromonomers are those that are endcapped with the ethylenically unsaturated moiety. By "endcapped" as used herein is meant that the ethylenically unsaturated moiety is at or near a terminal position of the macromonomer. However, this definition of "endcapped" is not intended to limit the macromonomer to only those macromonomers which terminate in a carbon-carbon double bond (whether mono-, di-, tri-, or tetra-substituted). The hydrophilic B macromonomers of the present invention can be synthesized utilizing a variety of standard synthetic procedures familiar to the polymer chemist of ordinary skill in the art. Furthermore, these macromonomers can be synthesized starting from commercially available polymers. Typically the weight average molecular weight of the macromonomer is from about 1000 to about 200,000, more preferably from 1500 to about 30,000, and most preferably from about 2000 to about 25,000. For example, the hydrophilic B macromonomers can be synthesized by the polymerization (acid, base, free radical, or auto-initiated) of a hydrophilic monomer to form a polymer which is subsequently reacted with or "endcapped" with a structural unit E, containing the ethylenically unsaturated moiety. Alternatively, the B macromonomers can be synthesized starting with commercially available hydrophilic polymers which are "endcapped" with the structural unit E. In yet another alternative, the B macromonomer can be synthesized by starting with the structural unit E, and polymerizing onto it the desired hydrophilic monomer units. It is to be understood that in this third alternative, the ethylenically unsaturated moiety of the E unit is not consumed in the synthesis but its integrity is preserved for subsequent copolymerization of the B macromonomer with the A monomer units. All of the synthetic alternatives are merely illustrative in that any other suitable synthetic procedures can be utilized to prepare the B macromonomers and copolymers of the present invention. The B macromonomers can be described by the following formula [ l ] n - [ X ] m - E. X is a hydrophilic monomer unit, and m is an integer from about 10 to about 2000, preferably from about 15 to about 300, and more preferably from about 20 to about 250, so that the macromonomer meets the weight average molecular weight requirements set forth above. Preferred is when X is a hydrophilic monomer unit selected from the group consisting of oxazolines, N-alkyloxazolines, alkylene glycols, N-vinylpyrrolidones, N- allylpyrrolidones, vinylpyridines, allylpyridiens, vinylcaprolactams, allylcaprolactams, vinylimidazoles, allylimidaoles, vinylfurans, allylfurans, vinyltetrahydrofurans, allyltetrahydrofurans, vinayiaminobenzenes, vinylaminomethylbenzenes, vinylaminoethylbenzenes, N,N- dialkylacrylamides, N,N-dialkyl(alkyl)acrylamides, and mixtures thereof.

It is to be understood that in the above structure, that when R 3 is other than hydrogen that various isomers of the resulting macromonomer are possible depending upon the orientation of the individual glycol moieties. Therefore, the structure depicted above for these endcapped polyalkylene glycol monolkayl ethers is a general one that is not intended to limit these materials to any one particular isomeric structure.

In the preceding structure, m is preferably an integer from about 10 to about 2000, more preferably from about 15 to about 300, and most preferably from about 20 to about 250. In the preceding structure it is found that pharmaceutically acceptable salts and quatemized derivatives are especially preferred because of their highly desired physical characteristics and solubility characteristics. By pharmaceutically acceptable salt as used herein is meant a salt that is generally regarded as safe for human use without undue risk of toxicity and other adverse effects. Nonlimiting examples of pharmaceutically acceptable salts of these materials include hydrochloride salts and hydrobromide salts. Nonlimiting examples of quatemized derivatives include alkyl quatemized derivatives wherein said alkyl group is a C1-30 straight or branched chain moiety, preferably a C1- 4 straight or branched chain moiety, more preferably wherein said alkyl group is methyl or ethyl.

These nitrogen containing endcapped macromonomers can be synthesized using standard synthetic procedures which involve polymerizing, usually under anionic initiation conditions the appropriate monomer unit, (e.g. 2-, 3-, or 4- vinyl pyridine, 4-dimethylaminomethyl vinyl benzene, etc.). A wide variety of initiators can be used, nonlimiting examples of which include bases such as n-butyl lithium, sec-butyl lithium, t-butyl lithium, lithium aluminum hydride, sodium hydride, and the like. Nonlimiting examples of these bases are provided in Anionic Polymerization: Principles and Practice. Maurice Morton, Chapter 2, p. 13, Academic Press, N.Y. (1983), which is incorporated by reference herein in its entirety. It has been found especially convenient to use these strong bases in conjunction with sterically hindered hydrocarbon materials such as 1,1-diphenyl ethylene to generate a sterically hindered base for inititiaing the polymerization reaction, in which case, the sterically hindered hydrocarbon is the actual initiator, defined previously as "I", which is incorporated into the macromonomer structure. Once the desired degree of polymerization is achieved, an appropriate endcapping reagent is typically used to terminate the polymerization and to endcap the macromonomer., nonlimiting examples of these endcapping reagents include 2-vinylbenzyl chloride, 3-vinylbenzyl chloride, 4-vinylbenzyl chloride, and the like. The pharmaceutically acceptable salts and quatemized derivatives of these nitorgen containing macromonomers are readily prepared from the macromonomers using standard synthetic procedures. Typically, the macromonomers are reacted with an acid to form the salt. For example reaction with hydrochloric acid or hydrobromic acid (either gaseous or as an aqueous solution) would yield the corresponding hydrochloride and hydrobromide salts, respectively. To form the quatemized derivatives the macromoners are reacted with a quatemizing agent. For example reaction with a methyl halide (e.g., methyl iodide, methyl chloride) or an alkyl sulfate (e.g. dimethyl sulfate, diethylsulfate) would yield the corresponding quatemized macromonomer. More typically, the pharmaceutically acceptable salt or quatemized derivative of the thermoplastic elastomeric polymer is desired, in which case the non-salt form or non-quatemized macromonomer is incorporated into the thermoplastic elastomeric copolymer, followed by salt formation or quatemization of the copolymer using standard synthetic procedures analogous to those described for the macromonomer. Also highly useful herein are endcapped hydrophilic polyacrylamide macromonomer units copolymerizable with A corresponding to the formula R 12 - [CH-CHR 13 ] m -E I c o I N (R 1 ) (Rl5) wherein E is a copolymerizable, ethylenically unsaturated moiety (i.e. the endcapping moiety).

Polymers of the Present Invention Particularly preferred polymers for use in the present invention include the following (the weight percents below refer to the amount of reactants added in the polymerization reaction, not necessarily the amount in the finished polymer): N-butyl acrylate/2-methoxyethyl acrylate/Poly(4-dimethylmino methylvinyl benzene) 38/22/40 Methyl quatemized N-butyl acrylate/2-methoxyethyl acrylate/poly(4- dimethylaminomethylvinyl benzene) 38/22/40 Ethyl quatemized N-butyl acrylate/2-methoxyethyl acrylate/poly(2- vinylpyridine) 38/22/40 N-butyl acrylate/2-methoxyethyl acrylate/Poly(2-vinylpyridine) hydrochloride 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(N,N-dimethylacrylamide) 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(N,N- dimethylmethacrylamide) 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(2-ethyl-2-oxazoline) 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(2-ethyl-2-oxazoline) 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(2-ethyl-2-oxazoline) 35/25/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(2-ethyl-2-oxazoline) 38/22/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(2-ethyl-2-oxazoiine) 38/22/40 n-butyl acrylate/poly(2-ethyl-2-oxazoline) 60/40 n-butyl acrylate/2-ethylhexyl methacrylate/poly(2-ethyl-2-oxazoline) 40/20/40 n-butyl acrylate/2-methoxyethyl acrylate/poly(ethylene glycol) 386/22/40 n-butyl acrylate 2-(dimethylamino)ethyl methacrylate/poly(2-ethyl-2- oxazoline) 36/24/40 n-butyl acrylate/methyl quatemized 2-(dimethylamino)ethyl methacrylate/poly(2-ethyl-2-oxazoline) 36/24/40 Synthesis of the Copolymers In general, the copolymers can be made by free radical polymerization of the A monomers with the B macromonomers. It is not intended to necessarily exclude from this invention any copolymers made by means other than free radical polymerization, so long as the product has the desired physical properties. The copolymers herein contain randomly repeating monomer units and macromonomer units. The general principles of free radical polymerization methods are well understood. See, for example, Odian, "Principles of Polymerization", 2nd edition, John Wiley & Sons, 1981, pp. 179-318. The desired monomers and macromonomers are all placed in a reactor, along with a sufficient amount of a mutual solvent so that when the reaction is complete the viscosity of the reaction is reasonable. Typical monomer and macromonomer loadings are from about 10% to about 50%, on a weight basis. Undesired terminators, especially oxygen, can be removed as needed. This is done by evacuation or by purging with an inert gas, such as argon or nitrogen. The initiator is introduced and the reaction brought to the temperature needed for initiation to occur, assuming thermal initiators are used. Nonlimiting examples of suitable initiators include those selected from the group consisting of azo initiators, peroxide initiators, redox initiators, and photochemical initiators. The polymerization is allowed to proceed as long as needed for a high level of conversion to be achieved, typically from a few hours to a few days. The solvent is then removed, usually by evaporation or by precipitating the copolymer by addition of a nonsolvent. The copolymer can be further purified, as needed utilizing a variety of techniques including filtration, extraction, trituration, membrane separation, gel permeation chromatography, and like. There are numerous variations on these procedures which are entirely up to the discretion of the synthetic chemist (e.g., choice of degassing method and gas, choice of initiator type, extent of conversion, reaction loading, etc). The choice of initiator and solvent are often determined by the requirements of the particular monomers and macromonomer used, because different monomers and macromonomers have different solubilities and different reactivities to a specific initiator. The copolymers of the present invention can also be synthesized by first presparing the backbone from the polymerization of suitable monomers, followed by further polymerization of the backbone with suitable hydrophilic monomers to form the polymeric side chains. This alternative procedure for synthesizing the copolymers herein is illustrated in EXAMPLE VII below. When salts and/or quatemized polymers are desired, these polymers are readily prepared from the copolymers using standard procedures, such as reaction with a strong acid or a quatemizing agent. Preferred among the acids are hydrogen chloride and hydrogen bromide, which can be employed either as a gas or as an aqueous solution. Commonly used quatemizing agents include alkyl halides (e.g., methyl iodide and methyl chloride) and alkyl and dilakyl suflates (e.g., dimethyl sulfate and diethyl sulfate). Analysis of the copolymer reaction product and the extracted materials, and the purified copolymer can be perfomred by conventional analysis techniques known in the art. These include, for example, nuclear magnetic resource (NMR), infrared molecular spectroscopies, gel permeation/size exclusion chromatography, membrane osmometry, and atomic absorption and emission spectroscopies. Hair Care and Topical Skin Care Compositions The copolymers of the present invention can be formulated into a wide variety of product types, including mousses, gels, lotions, tonics, sprays, shampoos, conditioners, rinses, hand and body lotions, facial moisturizers, sunscreens, anti-acne preparations, topical analgesics, mascaras, and the like. The carriers and additional components required to formulate such products vary with product type and can be routinely chosen by one skilled in the art. The following is a description of some of these carriers and additional components. Carriers Hair Care Compositions The hair care compositions of the present invention can comprise a carrier, or a mixture of such carriers, which are suitable for application to the hair. The carriers are present at from about 0.5% to about 99.5%, preferably from about 5.0% to about 99.5%, more preferably from about 10.0% to about 98.0%, of the composition. As used herein, the phrase "suitable for application to hair" means that the carrier does not damage or negatively affect the aesthetics of hair or cause irritation to the underlying skin. Carriers suitable for use with hair care compositions of the present invention include, for example, those used in the formulation of hair sprays, mousses, tonics, gels, shampoos, conditioners, and rinses. The choice of appropriate carrier will also depend on the particular copolymer to be used, and whether the product formulated is meant to be left on the surface to which it is applied (e.g., hair spray, mousse, tonic, or gel) or rinsed off after use (e.g., shampoo, conditioner, rinse). The carriers used herein can include a wide range of components conventionally used in hair care compositions. The earners can contain a solvent to dissolve or disperse the particular copolymer being used, with water, the C1-C6 alcohols, and mixtures thereof being preferred; and water, methanol, ethanol, isopropanol, and mixtures thereof being more preferred. The carriers can also contain a wide variety of additional materials inlcuding, but not limited to acetone, hydrocarbons (such as isobutane, hexane, decene), halogenated hydrocarbons (such as Freons), linalool, esters (such as ethyl acetate, dibutyl phthalate), and volatile silicon derivatives (especially siloxanes such as phenyl pentamethyl disiloxane, methoxypropyl heptamethyl cyclotetrasiloxane, chloropropyl pentamethyl disiloxane, hydroxypropyl pentamethyl di¬ siloxane, octamethyl cyclotetrasiloxane, decamethyl cyclopentasiloxane, cyclomethicone, and dimethicone having for example, a viscosity at 25oC of about 15 centipoise or less), and mixtures thereof. When the hair care composition is a hair spray, tonic, gel, or mousse the preferred solvents include water, ethanol, volatile silicone derivatives, and mixtures thereof. The solvents used in such mixtures may be miscible or immiscible with each other. Mousses and aerosol hair sprays can also utilize any of the conventional propellants to deliver the material as a foam (in the case of a mousse) or as a fine, uniform spray (in the case of an aerosol hair spray). Examples of suitable propellants include materials such as trichloro- fluoromethane, dichlorodifluoromethane, difluoroethane, dimethylether, propane, n-butane or isobutane. A tonic or hair spray product having a low viscosity may also utilize an emulsifying agent. Examples of suitable emulsifying agents include nonionic, cationic, anionic surfactants, or mixtures thereof. Fluorosurfactants are especially preferred, particularly if the product is a hair spray composition and most especially if it is a spray composition having relatively low levels of volatile organic solvents, such as alcohols, and relatively high levels of water (e.g., in excess of about 10%, by weight water). If such an emulsifying agent is used, it is preferably present at a level of from about 0.01% to about 7.5% of the composition. The level of propellant can be adjusted as desired but is generally from about 3% to about 30% of mousse compositions and from about 15% to about 50% of the aerosol hair spray compositions. Suitable spray containers are well known in the art and include conventional, non-aerosol pump sprays i.e., "atomizers," aerosol containers or cans having propellant, as described above, and also pump aerosol containers utilizing compressed air as the propellent. Pump ' aerosol containers are disclosed, for example, in U.S. Patents 4,077,441, March 7, 1978, Olofsson and 4,850,577, July 25, 1989, TerStege, both incorporated by reference herein, and also in U.S. Serial No. 07/839,648, Gosselin, Lund, Sojka, and Lefebvre, filed February 21, 1992, "Consumer Product Package Incorporating A Spray Device Utilizing Large Diameter Bubbles. Pump aerosols hair sprays using compressed air are also currently marketed by The Procter & Gamble Company under their tradename VIDAL SASSOON AIRSPRAYR hair sprays. Where the hair care compositions are conditioners and rinses the carrier can include a wide variety of conditioning materials. Where the hair care compositions are shampoos, the carrier can include surfactants, suspending agents, thickeners etc. Various additional components useful in hair care compositions are described in U.S. Patent No. 5,106,609, to Bolich, Jr. et al., issued April 21, 1992; and U.S. Patent No. 4,387,090, to Bolich, Jr. issued June 7, 1983; which are incorporated by reference herein. Some of these additional components are described below. Topical Skin Care Compositions The topical cosmetic and pharmaceutical compositions of the present invention can comprise a carrier. The carrier should be "cosmetically and/or pharmaceutically acceptable", which means that the carrier is suitable for topical application to the skin, has good aesthetic properties, is compatible with the copolymers of the present invention and any other components, and will not cause any untoward safety or toxicity concerns. The carrier can be in a wide variety of forms. For example, emulsion carriers, including, but not limited to, oil-in-water, water-in-oil, water-in-oil- in-water, and oil-in-water-in-silicone emulsions, are useful herein. These emulsions can cover a broad range of viscosities, e.g, from about 100 cps to about 200,000 cps. These emulsions can also be delivered in the form of sprays using either mechanical pump containers or pressurized aerosol containers using conventional propellants. These carriers can also be delivered in the form of a mousse.
